Robert B. Parker's The Devil Wins

In the wake of a huge storm, three bodies are discovered in an abandoned factory building in an industrial part of Paradise known as The Swap. One body, a man's, wrapped in a blue tarp, is only hours dead. But nearby are the remains of two teenage girls who had gone missing twenty-five years earlier. Things become even more complicated when one of the dead girls' mothers returns to Paradise to bury her daughter and is promptly murdered. It's up to Police Chief Jesse Stone to pull away the veil of the past to see how all the murders are connected.
